" Claims.

My invention relates to power heads.

It is the object of my invention to provide a power head that is completely self lubricated or simple and rigid construction, applying a, di-

' rect thrust to the piston rod of the pump and partlcularly'adapted for a double acting pump because of the uniformity of the application of the power in both directions.

It is my object to provide a power head in 1' which the guiding mechanism to impart vertical redprocatory movement to the piston oi'the pump from the rotary movement or the power head will be self lubricated,-but so arranged that such lubricant cannot splash into the pump II and contaminate the water.

It is a iurther object to provide a shifting box or plunger cylinder between the well tube, the piston rod and the power'head to provide for a perfect seal, easy replacement and quick ac- I0 cessibility. v

It he further object to provide a flywheel construction in the power head to give uniformity of movement, smoothness or operation and to' elimmate excess gearing and at the same time" 2 toprovide a crank for proper alignment and movement of the power transmitting mechanism.

It is an object to provide a. rectangular con--- nectlng link and a pair of parallel bearing shafts by which an. equidistantdistribution of the power, the thrusts and the strains isaccompitched, and by distributing the load in this manner, the minimum of size and weight of parts is It is a further object to provide not only a splash but a force teed lubrication system and a system oi long bearings lubricated so as to insure long life and self-contained action on the pert-of the pump'whereby it will require the minimum or attention. Y 4 It is a further object to provide means 101' the piston'rod of the pump. and the power head mechanism one with respect to the other by a single cross head against movement in tour directions so that perfect alignment will result. 7 Y

Figure 4 is a section on the line 4-4 of Figure 3;

Figure 5 is a section on the line ure 2.

nererring to the drawings in detail, 1 is the bottom of a casing having a forward wall towards the ump marked 2, a rearwall 3 and side walls 4 and 5. It is provided with a detachable cover 6. I

In the front and rear walls 2 and 3 are mount- 66 ed hollow stub shafts? and 8. On the'shaft '7 is mounted the gear 9 which is driven by, the pinion 10 from the power shaftll that is jour naled in the front and rear walls or the casing as at 13 and 14. This power shaft extends outside of the casing and is driven by any suitable source of motive power.

The other stub shaft 8 carries a flywheel disk 15. Mounted on thisfiywheel disk and on the gear 9" and connecting them together is a transverse bearing shaft 16 mounted in sleeves 1'7 and 18 of the gear 9 and flywheel 15 respectively and pinned thereto by the pins 19. Between'these sleevesand mounted upon the bearing shaft 16 is an elongated bearing sleeve 20 of a rectangu- 80. larpitman which is composed of the spaced arms 21' and'22 mounted on the sleeve 20 and connected at their upper ends by a similar sleeve 23 which carries the bearing shaft 24. This bearing shalt has on one end thereof the detachable 86 screw.25 carrying the retaining plate 26 that engages the end of the bearing sleevei23. The top of this sleeve 23 is provided with a channel 2'? iorthe distribution or lubricant to the ports 28 and 29 so that the lubricant can have access to the interior of the sleeve 23 and the shaft 24. The method of distributing this liquid to this channel 2'7 is described hereinafter.

a The shaft 24 projects out of the main casing through a slot 30 in the trout wall 2 or the main casing. The bottom or this slot is provided with an outwardly extending drain lip 31 for drain- 5-5 of Fi ing any lubricant 'back into the main casing which may drip from the side walls of the slot whichare grooved at 32 for receiving the sides 33 of the cross head 34 that is pinned to the shaft 24 by the pin 35. This cross head is guided by the side walls 32 at the slot 30 in" a vertical path. The extension of the shaft 24 through the cross head carries a sleeve 36 which is piimed to the shaft 24 bythe set screw 3'1. This sleeve has threaded into it at 38, the upper end of the piston rod 39. The sleeve is also provided with a deflector lip 40 for deflecting lubricant from the crosshead slide back into the main casing where the lubricant is contained. The piston rod 39 passes through a packing gland 41 and a packing 42 contained in the packing sleeve 43 that is supported on the top of the L-shaped fitting 44 that is threaded upon the well tube 45 at the top thereof. The side of this fitting is threa'ded to the delivery pipe 46. with a pair of laterally extending flanges 47 which are bolted by the bolts 48 to the front of the casing. The lower sides of these flanges 47 rest upon the shoulder 49 of the casing.

The piston rod at its upper end and the extended end of the shaft 24 are enclosed by a detachable housing 50.

It will be understood that lubricant is-contained in a pool for splash lubrication as at 51 and it also has a supply of lubricant for forced lubrication through the delivery pump hereinafter described.

This delivery pump consists of a stationary tube 52 having inlet apertures 53 through which lubricant is drawn from the pool 51 by the suction of the pump plunger 54 which reciprocates within the tube. This pump plunger 54 has a hollow tube having an aperture 55 at the bottom formed by a threaded closure member 56. This aperture'55 is adapted to be closed on the upstroke by a loose ball 57. This serves to deliver lubricant in a stream through the horizontal L-pipe 58 to the four-way fitting 59 which has two branches 60 and 61 delivering lubricant to the cross head slides while the other branch 62 delivers lubricant tothe channel 27. The stationary tube 52 is attached by some suitable means such as a loop 52! to the front wall 2 of the casing. The'movable part 54 of the pump is attached to some part of the pitman head' so that asthe pitman moves up and down the pump will operate. This attachment is effected by means of a loop 54'. The reciprocating piston of the lubricating pump is attached to and operated through the sleeve by means of an attaching. V

i head carried by said pitman, cross head guides formed by spaced walls surrounding a slot in the strap 54.

Thus, the splash and force feed lubricationis It will be understood that I desire to comprehend within my invention such modifications as.

may be necessary to adapt it to varying conditions and uses. r
